EGG-BEATER.

Specification of Letters Patent.

Patented July 12, 1.321.

Application filed December 27, 1920. Serial No. 433,274.

To all whom it may concern:

Be it known that I, J .nuns L. BRUMFORD, a citizen of the United States, residing at Canajoharie, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in an Beater, of which the following is a speci fication.

The invention relates to an egg beater, and has for its primary object to provide a heater of the indicated character, wherein the agitator elements are arranged opposite each other and rotate in reverse directions so that the beater when actuated will thoroughly agitate the material acted upon, the lingers of the agitator elements being of novel form and assembled in a unique manner to assure strength and durability, and the assemblage of the fingers relative to each other of said elements being such as to assure compactness and also efficienlzv in the operation of the beater.

Another object of the invention is the provision of a beater of this character, wherein the power shafts for actuating the agitator elements are assembled in a unique manner and are driven or operated in reverse directions, the agitator elements being connected to the power shafts so as to be positively turned thereby and the agitator lingers thereof are assembled relative to each other to effect etlicacious agitating or beating action in the use of the beater. A further object of the invention is the provision of a beater of this character, which is comparatively simple in construction, possessing but few parts readily and easily assembled, thoroughly reliable and efiicient in its operation, strong, durable and inexpensive to manufacture.

With these and other objects in view, the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation partly in sections of a beater constructed in accordance with the invention.

Fig. 2 is an elevation showing the power wheel in plan.

l ig. 3, is a fragmentary detail transverse sectional view through one of the agitator elements showing the mounting of the agitator fingers.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the egg beater comprises a substantially U shaped bracket 5, constituting the body frame which has journaled longitudinally thereof, in the upper and lower limbs 6 and T of the same power shaft 8, the same being of the required length and has fixed to one end of the same eXteriorly of said frame, a pinion 9, while carried on the opposite end of said shaft 8 is an agitator element hereinafter dcscribed.

Fitted upon the power shaft 8 is a tubular power shaft 10, the same being located outside of the frame 5 and carries at its inner end a pinion 11, while mounted in the frame 5 medially thereof is a stationary stub 12, constituting a bearing which is disposed crosswise of and at right angles to the power shaft 10 carries an agitator element which comprises a hub formed with an inner core 16 and outer shells or covering sections 17 and 18 respectively, the shell or covering section 17 being of inverted substantially cup shape, to receive the core 16 and is made fast to the shell or section 18 through the medium of overlapped interlocked marginal flanges 19 formed on said shells or sections 17 and 18 as is clearly shown in Fig. 1 of the drawings.

Mounted in the hub by engagement in the core 16 are opposed outwardly and downwardly curved agitator fingers 20, which are integrally formed in pairs and extend through suitable openings formed in the shell or section 17 to overlie the interlocked flanges 19.

The agitator element carried by the power shaft 8 which is similar and inverted with respect to the agitator above described comprises a hub including a core 21 and outer shells or covered sections 9.2 and 23 respectively, the section 22 receiving the core 21,

the sections 22 and 23 being connected-to-.

gether through the medium of interlocked flanges 2 1, formed thereon, while engaged in the core 21 are agitator fingers 25, the same being integrally formed iiipairs and extend through the shell or section 22 come spondingly to the fingers 20, the detailed mounting of the fingers being shown in Fig. 3 of the drawing. The fingers 25 are bent outwardly and upwardly to lie inwardly of the path of movement of the fingers 20.

The hubs of the agitator elements including the cores 16 and 21 and the shells or coveringsectioiis are made fast'to the respective shafts 8 and 10 toturntherewith, the shaft 8 being formed with nibs 26 to lock the core 21 thereon, while the shaft 10 may be likewise fixed to the core 16 or thelatter fastened in any other manner.

On manually operating the gear 13 motion is transmitted through the pinions 9 and 11 to the respective shafts 8 and 10 for driving the same in reverse direction and likewise the agitator elements will be reversely rotated one within the other, the fingers 25 being designed to travel inwardly of the path of movement of the fingers 20-during the operation of thebeater and said fingers of the agitator elements will serve efiicaciousl y for agitating or beating purposes.

The heater in its construction assemblage renders the same compact and is readily operated.

What is claimed is:

1. An egg beater of the character described comprising a support, a power shaft rotatablymounted in said support, a second tubular power shaft rotatably mounted on the first named shaft, complementary agitating elements inverted witlirespect to each other carried by the ends of the respective shafts, eachofsaid elements comprising a core, a sectional shell embracing said core,

curved agitating fingers integrally formed in pairs mounted in the core and projecting through the shell, the free ends of the ag'b tator fingers of one element being inwardly disposed ofthe path of movement of the free ends of the agitator fingers of the other element and means for simultaneously rot ating said shafts in opposite directions.

2. An egg beater of the character 'described con-iprising a support, a power shaft rotatably mounted in said support, a second 3. An-egg beater of the class described comprising a power shaft, atubular shaft rotatably mounted on the power shaft, agitating eleinents'inverted with respect to each other carried by said shaft, each of said elements consisting of a core, a'shell embracing said core, curvedagitatingfingers mounted in the core and'pi'ojecting througlithe shell, the fingers of one element being inwardly disposed of the path of movement of the fingers of the other elements.

in testimonywhereof I a'fiix my signature hereto.
